said spindle. Said spindle enters the vapo- I vvaporization; second, to provide means for precipitating impurities of the hydrocarbon and preventing the access of said impurities to the valves and burner; third, to provide a receptacle for retaining said impurities, which receptacle may be readily removed andl cleansed or renewed; fourth, to provide means for keeping the passage in the needle-valve clear of obstructions; fifth, to provide means for adjusting the globe, and, sixth, to provide the other details hereinafter set forth. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Y.

parts throughout the s everal views.

Theinlet-valve seatais connected tothe supply-pipe o by means of the coupling b' andl is connected to the cylindrical vaporiZer-casing cby means of the .coupling ct. The inletvalve dseats upon'said valve-seat and spreads toward the bottom for the purpose of'distributing the hydrocarbon as it enters the vaporizer. Said valve is formed at the upper extremity of the valvevstem c, and said valvestem is raised and lowered by means of the rack e thereon, which is engaged by the pinion f. Said pinion is secured on the spindle f' by means of the nutfz and is rotated by rizer-casing c through the stuffing-box e2 on said casing.

The settling-well g is a vessel consisting, preferably, of two concentric cylinders completely joined at the bottom and open at the top,'the outer cylinder fitting within the vaporizer-casing c andresting upon the shoulder c', formed at the bottom of said` casing where joined with the tubular extension c2 of the casing. By preference the outer cylinder of said well is of an equal height with the casing c, while theinner cylinderis of a height somewhat less, in order to permit the hydrocarbon to liow over the top thereof. The diameter of the valve-stem e is less than the inner diameter of the settlinggwell, thereby affording a passage for hydrocarbon therebetween.

`Acylindrical separator h, equal in height with the casing c, is placed concentrically Within said casing and is of such a diameter as to occupya position between the inner and outer cylinders thereof. I Said separatorl is closed at the top except where it receives the valve-stem e, and consequently there is a passage between the top of saidseparator and the top of the inner cylinder of the settlingwell. Said separator rests upon the bottom of the settling-well, but is provided with apertures-h' near the bottom, which afford a passage for the hydrocarbon. The greatest diameter of the valve d is approximately as great as the diameterof said separator, and in operation the hydrocarbon is distributed by saidvalve d to thec'hamber between the separator and the outer cylinderofthe set- Strainers- 1l are provided in the settling-well g for preventing as far as possible foreign material. from entering the interior parts lof the device. A

In ord er to hold the separator h in its proper position within the well, said separator is provided with the spacing-wings h2 h2, as. best shown in Fig. 6. VThe flange or foot h3 is formed at the bottom of the separator h and constitutes a false bottom' to the settling-well.

Another purpose of said wingsis for cleaning the settling-wellg. This is accomplished by rotating said separator by hand, which causes said Wings to scrape the sides of the IOO well and remove any matter which may have adhered thereto. 'lhe settling-well g and separator 7L do not require to be fastened in position, and ou account of their simple coustructiou cou nterparts may be readily substituted. As these parts ot' the vaporizer are the ones most liable to become clogged, the propel' renewal ot' these parts will indefinitely prolong thelife of the device.

The vaporizer-casiug c slips in to and is supported by the socket j, which in the present instance comprises the rings j' and jg, suitably connected together, so as to retain said casing and the parts attached thereto. At the upper extremity ot' said socket. is formed a shield jg for preventing the heat of the burner from damaging the upper extremity of the casing. The flanged periphery of said shield is apertured to receive the rods 7c 7c, whereby said socket and its appendages are suspended. A set-screwj1 is provided in the ringj2 for securing said casing c in position. Said shield is also provided with arms for suspending the inautles m. The ringj is rigidlysuspended from the socketj and is interiorly threaded to be coupled with the mixing-chamber a, hereinafter described. The extension c2, screw-connected with the lower extremity of the casing c, is coupled at its lower extremity to the needle-valve seat 0. VV'ithin said extension is placed the liningtube d, which is screwed into the lower' extremity of the inner portion of the settlingwell g. The purpose in providing the said lining-tube attached to said settling-well is to afford a ready means for keeping the passage around the valve-stem e clean, lf said extension becomes clogged, it maybe withdrawn by lifting out the well g and then unscrewing said lining-tube and either cleansing the saineorsubstitutinga new tubeiu lieu thereof. The valve-stein e extends downward through said tube o and at its lowel extremity forms a valve for closings-aid valve-seat o. The latter is chiefly for emergency use-to quickly shut olf the supply of vapor from both burners and extinguish the flame. Then thus used, as soon as combustion has ceased the Valve-stem may be raised and the valve d closed, thus preven t in;r the settling well from becoming iilled with liquid. A wire p is attached to the lower extremity ot` the stein ein such a manner as to pass through the needleaperture in the seat o and is of an exceedinglysmall diameter,so as to permit the passage of vapor through the valve-seat when said wire occupies a position therein--that is to say, said wire does not completely [ill the aperture iu the valve-seat 0. By this construction the rotation of the spindlef' notonly opens and closes the valve-seats ct and 0, but also cleans the latter by working up and down and loosening any obstructing material which may-have adhered to the sides of the aperture therein. It will thus be seen that the valvestem e and its adjuncts have three separate functions-ii-st, to control the supply of liq-` uid entering the vaporizer; second, to operate as an emergency-valve, and, third, to at'- ford means for cleaning the valve-seat o.

The mixing-chamber n screws into the ring j and is provided with a series of apertures` p' for admitting the air. Said mixing-chamber has a shoulder n' formed thereon for supporting the preheatingcup q. Said cup is loosely mounted ou said mixingchamber, so as to be revoluble on said shoulder l1?.,and is provided with a series of apertures q' for regulating the supply of air through t he apertures p' in the chamber n. Said cup is controlled by means of the rod r, and the parts are so related that the valve-seat o discharges into the mixing-chamber n above the aire-aportures p.

The burner-pipes s s screw onto the lower extremity of the mixing-chamber n and extend upward, so that the mouths thereofl are somewhatbelowthe vaporiZing-casingc. The mouths of said pipes are, however, close enough to said casing to heat the same to a degree sufficient to vaporize the hyd rocarbou entering thereinto. The flames issuing from the mouths of said pipes s will also heat the exposed tubular extension c2. A valve s is provided in each of said pipes for shuttingr off the supply of vapor to the burners when desired. At the mouths of said pipes are placed the spreaders .s2 s2, and the ganzes s3 are also desirable at said months. At the lower' extremity of said burner-pipes is the interiorlyscrew-threaded boss t, which receives and supports the downwardly-extending rod u. At its lower extremity said rod screws into the socket 'u' of the handle c.

The globe-holder w is provided with the annular groove w' for receivingr the lower eX- tremity of the globe and is also provided with the sleeve portion to2, which incloses the rod u and is of a sufficient interior diameter to inclose the handle c. A shoulder lw3 is formed at the upperextremity of said sleeve for engaging the upper edge of the socket fu when theglobe-holderislowered. Aset-screw wl is provided in said holder for securing the same at any desired height on the rod tt. Thus the parts are so arranged that when it is desired to renew the mantles m the holder L0 may be lowered until the shoulder-w3 rests upon the socket fv; but under normal conditions the globe may beheld at any height desired.

It is desirable to provide means for removing liquid which from any cause may collect at the bottom ofthe burner-pipes s. For this purpose an annular recess 'Lt' is formed at the upper extremity of the rod u. In case liquid collects in said pipes s said rod is unscrewed from the bosstand lowered a slight distance, and the liquid may then pass out through the passage thus opened. In order to suspend said rod u at the right height to permit the escape of liquid and at the same time prevent the upper extremity of said rod from leaving said boss, both said boss and rod are provided with tot,

pins y y, which are adapted to be engaged by the links or hooks z. By this construction there is no danger of the rod u becoming entirely detached at the risk of breaking the globe 0o.

The stack A is suspended above the mamies by any suitable means and carries the shadeholderB for supporting 'the shade C in the.

connected to said settling-well; and a Valveusual manner.

' In operation when thevalve d is open liq` uid hydrocarbon enters from the pipe b and is spread by said valve, so as to'enter the settling-well g outside of the separatorih. ASaid well and the casing c are hot, being heated at starting by iiames from the preheating-cup q and subsequently by flames from the burnerpipes s. The hydrocarbon upon entering said hot settling-well and being distributed to all portions thereof by said valve is more or less completely vaporized at once and passes to the bottom of said well, thence through apertures h at the lower extremity-of the separator h, thence upward inside of said separator, over the top of the inner wall of the settling-well, and thence downward through the needle-valve o to the mixing-chambern, finally emerging from the mouths of the burner-pipes, where vaporization is complete and ignition takes place. The motion ofthe liquid downward in the settling-well g is slow, for the reason that the passage outside of the separator h is comparatively large. This permits the im purties, which are of greater speciiic gravity than the hydrocarbon, to settle at the bottom of said well and there remain, being un'inuenced by the slowlyupwardmoving current inside of said separator.

If the needle-Valve seat ois obstructed, the

stem e is raised and lowered a -few times, whereupon the wire p will dislodge the obstructions and permit afree flow. When impurities have collected to an extent sufficient Ato clogthe passages, the vnut f2 is unscrewed from the spindlef and the latter withdrawn to permit the disassem bling of the parts. After the stem e is `removed' the settling-well g is withdrawn from the casing c, bringing with it the separatorh and lining-tube o. The tube is then unscrewed and cleansed or renewed, and the separator is rotated within the well g, the wings h2 acting as Scrapers. This loosens the obstructions in sai-d well, and the foot or ange h3 will carry with it the obstructions uponthe withd rawal of the separator h from said well.

It will be understood that the construction i of many of the parts described may be varied stem cooperating therewith.
